Never put those cheap ass Autolite plugs in... With that said, copper NGK plugs (brk6e) are great plugs...I was running the NGK -1 range cooler plugs (bkr7e) until the last GIAC update...and was pleasant pleased with the quality of the plugs...especially for $1.50 a piece!
within the past six months, off the top of my head, i had the following done at tyrolsport : timing belt water pump thermostat oil cooler and housing all new coolant hoses.. thats right.. i did it just cause.. i have the reciepts. valve cover gasket cam tensioner gasket ngk pfr6q's see where this is going?
i felt the same hesitation with my car. i did a scan and got some cylinder misfire faults so i changed my spark plugs to the NGK 1 heat range colder and i havent felt that hesitation since.
I used the NGK BRK6E V-power plugs, and from what I understand those are highly recommended, and I did switch the coilpacks from cyl 1&2. it's weird because I had many misfires before the CEL was thrown.
I know I use the cheap copper NGK B8ES plugs. Who cares if I have to replace them every oil change. For $1.79 who cares
I changed the plugs thinking that what it was. (it was not). I thought it was the coil packs so I bought a new set of four, which I have NOT installed yet.
I'm going to keep using NGK's though. The farm-supply store has a whole aisle of them and they're all $1.59 each . I've put them in vehicles where the OE's are Delco, Bosch, Champion, Motorcraft, or Denso and they've all run perfectly with the NGKs.
Out of all the plugs I've tried, standard NGK V-powers are the only ones that have consistently worked well in *everything* I've stuck them in. From single-cylinder lawnmowers to high-winding Japanese 4s to domestic and imported V6s to big-inch V8s. They're worth the extra 40 cents over Champs or Autolites.
When I switched to NGK's it seemed to run better
I just put new plugs in (NGK Iridium IX) and the engine does not shake/miss fire as much as before.
